Meghan Markle is channeling a nostalgic part of her past for her and Prince Harry’s latest project.

The Duke and Duchess of Sussex are set to executive produce Cookie Queens, a documentary that spotlights “a coming-of-age story about the joys, pressures, and pain points woven into one of America’s most cherished rituals: Girl Scout Cookie season,” per Deadline.

Directed by Alysa Nahmias, the doc is set to premiere at Sundance in 2026 as part of the festival’s Family Matinee section.

“Captivating, candid, and full of heart, the film follows four girls ages 5 to 12 and their families as they navigate the annual whirlwind of selling, striving and succeeding,” notes a description of Cookie Queens.

“For these Girl Scouts, selling cookies isn’t just about Thin Mints and sisterhood — it’s a crash course in entrepreneurship. Behind the smiles and cookie boxes lie real pressure: long hours, ambitious sales goals, and the weight of high expectations. Nahmias crafts a bold, vibrant, observational portrait that honors the girls’ perspectives and illuminates the emotional and intellectual stakes of their experiences.”

The project is especially nostalgic for Meghan, who was a Girl Scout herself while growing up in California.

Meghan said in a statement, according to Deadline, “As a former Girl Scout myself, with my mom as my troop leader, I have a personal affinity for this film and am proud that all our conversations and collaboration have led to Archewell Productions partnering with this award-winning team to executive produce this incredibly captivating documentary.”

“When we first viewed the early footage of this documentary, it was immediately something we wanted to be involved in,” she added. “The creative point of view, the edgy yet humanizing tone and tenor of the directing, and the glimpse behind-the-scenes into such a nostalgic and also modern tradition of Girl Scout Cookie season are absolutely irresistible.”

Back in April, the Duchess of Sussex shared throwback pictures of herself selling cookies in her scout uniform to celebrate the launch of her Lemonada Media podcast, Confessions of a Female Founder .

“Being an entrepreneur can start young. (By the way, all these years later, and I’m still selling cookies!) 🍪,” Meghan wrote, also alluding to her As ever shortbread butter cookies, just a few days after the brand’s first launch sold out in under an hour.

In the photo, Meghan’s brown uniform identifies her as a “Brownie,” the Girl Scouts of the USA level for 2nd and 3rd graders, which would make her around 7 to 9 years old.

Meghan and Harry’s Archewell Productions is partnering with Beautiful Stories and AJNA Films on the documentary.

The Duke and Duchess of Sussex signed a deal with Netflix in 2020 for a reported $100 million. They revealed in August that they are extending their creative partnership through Archewell Productions with a multi-year, first-look deal for film and television projects.

The documentary announcement comes just over a week after Meghan’s Netflix Christmas special, With Love, Meghan: Holiday Celebration, dropped on Dec. 3.

The hour-long special showed Meghan crafting with tennis champion Naomi Osaka, cooking gumbo for chef and Top Chef judge Tom Colicchio and having a festive brunch with her longtime friends Kelly McKee Zajfen and author-producer Lindsay Jill Roth.

Prince Harry even makes a brief cameo towards the end of the hour, sharing a sweet kiss with his wife as he helps himself to some of the treats in their kitchen.

PEOPLE spoke with Roth about filming her segment last week. She said it was great to see her longtime friend in her element in the kitchen, adding that the smells of Christmas all around made it extra special.

“The vibe was amazing,” Roth said. “It instantly felt like a family day. So warm, so fun, so easy. We were just ourselves.”
